WORK CONVEYING AND PRESENTING MECHANISM.

Y SPECIFICATION forming part of Letters Patent No. 694,467, datedMarch4, 1902.

Application filed April 5, 1901.

T0 at whom it ,mctycmwern:

Be it known that I, RUSSELL B. FULLER, a citizen of the United States,residing at Holland, in the county of Ottawa and State. of Michigan,have invented certain new and useful Improvements in Work Conveying andPresenting Mechanism; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in mechanisms for conveying andpresenting the materials to be operated upon to nailing-machines,presses, andlike machines; and the particular device herein shown andillustrating my invention is especially adapted to operate inconjunction with a nailing-machine, and the material operated upon, asshown, is basket-tops to be used with what'iscommonly known as theClimax? fruit-basket. V

The object of my invention is to provide the automatiomeans forconveyingthe stock to be operated upon with improved means for holdingthe same in place While being nailed or otherwise operated upon by themachine and automatically releasing and discharging the stock after ithas been operatedupon.

My invention consists, essentially, in providing the machine having anendless belt or apron consisting of narrow transverse slats flexiblyconnected in series and traversing the bed of the machine and providingcertain groups of these slats with improved holding means to engage'theopposite sides of material to be operated upon and in certain details ofconstruction and arrangement ofparts, as hereinafter more fullydescribed,and particularly pointed outin the claims, reference being hadto the accompanying drawings, in which- Figure 1 is a longitudinalvertical section of a device embodying my invention, taken on the line 11 of Figs. 2 and'3; Fig. 2, a transverse section ofthe same on the line2 2 of Fig. 1; Fig. 3, a plan of one group of slats and the stocksupported thereby; Fig. 4, an

perspective of a finished machine, press, or other analogous machine; B,the nailing-head or other operating member of the machine'adapted tonail .or otherwise operate upon the stock.

A is an extension of the bed A, above which extension the stock isplaced and assembled in the holders.

O C. are V-tracks on the beds A and A, on which tracks the apron ismovably supported. This apron consists of a continuous series oftransverse slats F, attached to the links of endless sprocket-chains E,one slat to opposing links infthe respective chains.

At each end of the bed or table A A are sprocket-Wheels D, engaging-thesprocketchains E and mounted on shafts D D, one

A represents the bed or table of a nailing-- of which shafts is providedwith any convenient means (not shown) of imparting intermittent rotarymotion thereto suificient to carry the apron forward at each movement asuitable distance to successively bring each basket-top or other articleunder the member B.

Upon the'bottom of each slat Fare blocks G, having \l -grooves to fitthe track 0 and slide thereon. These blocks and tracks also afford asolid support to sustainthe pressure or blow exerted by the member B. Inthe de- -.vice shown, each successive group of four slats constitute asection adapted to hold the material fora basket-top and is providedwith the following means for holding the same: blocks H, havingprojections I to engage the "respective sides of the top strips J andhold the same in place, posts N to engage the ends of the segments K,springs M to engage the ends of the segments opposite the posts N. Theseposts N and springs M are attached to the outer sides of the outer slatsof the group and upwardly-projecting pins L also inserted in the slatsto engage the outer side of the segments K and properly locate the same.

Beneath the middle of each segment is a conical thimble O to receive alongnail P, used to secure the top in place on the basket. Thesethimbles are embedded in the adjacent sides of the middle slats, (of thegroup of four,) onehalf in each, and secured to one slat only by asuitable screw or fastening, as shown in Fig. 4.

The extension A and the apron are made of sufficient length toaccommodate a sufficient number of operators to place the stock in theholders as the apron traverses the extension A. The segments K and topstrips J will all be securely held as long as the apron is in ahorizontal plane, and when a group of slats pass over thesprocket-wheels D said slats are separated and project radially from theaxis of the shaft D. This position separates the holding means andautomatically discharges the stock therefrom.

From the foregoing description the operation of my device will bereadily understood without further explanation.

Having thus fully described my in vention,

what I claim, and desire to secure by Letters Patent, is

1. The combination of sprocket chains, wheels engaging the chains,transverse slats attached to opposing links in the chains and arrangedin groups, posts attached to a slat at one side of the group, springsattached to a slat at the opposite side of the group, pins in the slats,and blocks on the respective slats and having upward projections toengage opposite sides of the stock, substantially as described.

2. In combination with a nailing-machine, an endless apron, consistingof transverse slats pivotally connected to each other and arranged ingroups of four, one slat having posts pins, and blocks, to engage oneside of the stock, one slat having springs, pins, and blocks to engagethe opposite side of the stock, two of said slats having blocks toengage the stock, and thimbles between the middle slats and attached toone of the same, substantially as described.

3. The following means for holding baskettops to be nailed: four slatspivotally connected to each other in series, posts at one side of theseries to engage the ends of the segments, springs at the other side ofthe series to engage the opposite ends of the segments, pins in theouter slat-s to engage the outside of the segments, and blocks on eachslat having upward projections to engage the opposite sides of the topstrips, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
